ME2DP for asset can't be processed by F110

We use PO to do asset acquisition and use ME2DP to do process down payment requests.

Then we need to pay the downpayment by using F110.

But it comes to an error AA866, and lead me to configure the Acquisition: down payments account which we actually don't need to capitalize asset through downpayments.

How to aviod this error?

kindly help.

Thanks a lot.
